I wonder what is the difference between efficiency of MacBook display vs Framework laptop. Whilst CPU and GPU take considerable power they aren't usually working at 100% utilization. Display however has to be using power all the time, possibly at high brightness in daytime. MacBooks have (all?) high resolution displays which should be much power hungrier than Framework 13 IPS. Pro models use mini LED, which needs even more power.

I did ask LLM for some stats about this. According to Claude Sonnet 4 through VS Code (for what that's worth), my Macbook's display can consume same or even more power than CPU does for "office work". Yet my M1 Max 16" seems to last a good while longer than whatever it was I got from work this year. I'd like to know how those stats are produced (or are they hallucinated...). There doesn't seem to be a way to get display's power usage in M series Macs. So, you'd need to devise a testing regime for display off and display on 100% brightness to get some indication of its effect on power use.
